[nos-bbs] my poor TEKK radio - dangers of a baycom driver

[Kerry Smith]

Yep, use a 555 timer ckt on the ptt line, you should be
able to set the duration to almost anything, then if it
does die in the tx mode, after so long, the 555 kicks it
out and it won't reset until the ptt is relased for the reset.
